Description

Technical Field

[0001] This utility model mainly relates to the field of triaxial mixing pile construction technology, specifically a reusable device for controlling the verticality and elevation of triaxial mixing piles. Background Technology

[0002] During the on-site construction of triple-axis mixing piles, the excessive size of the equipment made it difficult to accurately control the verticality of the H-shaped sheet piles after they entered the soil. Furthermore, the excessive vibration amplitude of the vibratory hammer made it difficult for workers to control the insertion depth, failing to meet construction specifications. Consequently, the insertion depth and verticality did not meet expectations, resulting in poor sheet pile formation and a risk of leakage later on. Utility Model Content

[0003] The purpose of this invention is to provide a reusable device for controlling the verticality and elevation of a triaxial mixing pile, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a reusable device for controlling the verticality and elevation of a triaxial mixing pile, comprising a vibratory hammer, wherein the top end of the vibratory hammer forms a connecting part for connecting to an external robotic arm, and the bottom end of the vibratory hammer forms a clamping part for clamping an H-shaped sheet pile, wherein a connecting seat is provided on the outer wall of the vibratory hammer, the top of the connecting seat is slotted and a return spring, a limiting plate and a threaded seat are sequentially provided from the bottom to the top of the slot, a locking bolt is threaded onto the threaded seat, a sliding strip is provided at one end of the limiting plate, the sliding strip penetrates the connecting seat and is connected to a scale plate, and a verticality measuring instrument is detachably provided on the scale plate.

[0005] Preferably, the threaded seat has a boss-shaped structure, with a portion protruding into the top groove of the connecting seat, and the remaining portion abutting against the top of the connecting seat and having a connecting screw on top to connect and fix the threaded seat and the connecting seat. The center position of the threaded seat forms a threaded groove in the vertical direction that matches the locking bolt.

[0006] Furthermore, the limiting plate has an inverted L-shaped structure, with the upper and lower ends of its L-shaped horizontal axis tightly abutting the locking bolt and the return spring, respectively. When the threaded seat is removed and the return spring rebounds into its natural state, the L-shaped horizontal axis of the limiting plate is exactly above the top slot of the connecting seat, and the L-shaped vertical axis of the limiting plate is connected and fixed to the sliding bar.

[0007] Preferably, a movable groove is formed on the side wall of the connecting seat from top to bottom, the depth of the movable groove is the same as the groove depth at the top of the connecting seat, and the sliding strip fits into the movable groove.

[0008] Preferably, the scale plate has elevation markings on both sides along the vertical direction.

[0009] Preferably, the verticality measuring instrument has multiple first connecting screw holes, and the scale plate has multiple second connecting screw holes, wherein the number of first connecting screw holes and second connecting screw holes are the same and they correspond one-to-one.

[0010] Preferably, the verticality measuring instrument is provided with a digital display screen on the side opposite to the vibratory hammer.

[0011] Compared with existing technologies, the advantages of this utility model are as follows: This utility model provides a reusable device for controlling the verticality and elevation of a triaxial mixing pile. By setting a connecting seat on the outer wall of the vibratory hammer and employing a series locking mechanism of "reset spring - inverted L-shaped limiting plate - threaded seat - locking bolt," a scale plate with elevation markings and a detachable verticality measuring instrument mounted on it are rigidly fixed to the vibratory hammer. In the locked state, this locking mechanism effectively resists the severe vibrations of the vibratory hammer during operation, ensuring the stability of the measurement benchmark and the reliability of the data. Simultaneously, by loosening the locking bolt, the height of the scale plate can be flexibly adjusted using the reset spring or manual assistance, through the cooperation of the sliding strip and the movable groove, to adapt to different working conditions. The verticality measuring instrument and the scale plate, as well as the entire measuring module and the connecting seat, are detachable (threaded connection, sliding fit), allowing key measuring components to be easily disassembled and reused in different pile locations or projects.

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1 to 3 As shown, a reusable device for controlling the verticality and elevation of a triaxial mixing pile includes a vibratory hammer 1. The top of the vibratory hammer 1 forms a connecting part 3 that connects to an external robotic arm, and the bottom of the vibratory hammer 1 forms a clamping part 2 to clamp an H-shaped sheet pile 4. A connecting seat 5 is provided on the outer wall of the vibratory hammer 1. The top of the connecting seat 5 is slotted, and a return spring 17, a limiting plate 9, and a threaded seat 10 are sequentially arranged from the bottom to the top of the slot. A locking bolt 11 is threaded onto the threaded seat 10. A sliding strip 16 is provided at one end of the limiting plate 9. The sliding strip 16 penetrates the connecting seat 5 and is connected to a scale plate 6. A verticality measuring instrument 7 is detachably installed on the scale plate 6.

[0023] The threaded seat 10 has a boss-shaped structure, with one part protruding into the top groove of the connecting seat 5, and the remaining part tightly abutting the top of the connecting seat 5. A connecting screw 18 is provided on the top to connect and fix the threaded seat 10 and the connecting seat 5. The center of the threaded seat 10 forms a threaded groove in the vertical direction that matches the locking bolt 11. The threaded seat 10 allows the locking bolt 11 to be fixed at the top of the connecting seat 5, and the insertion depth of the locking bolt 11 can be adjusted according to the number of rotations of the locking bolt 11. However, to avoid the locking bolt 11 becoming too loose and dislodging from the threaded seat 10, the length of the locking bolt 11 pulled out from the top of the threaded seat 10 should not exceed fifty percent of its total length.

[0024] The limiting plate 9 has an inverted L-shaped structure. Its upper and lower ends, at the horizontal axis position, abut against the locking bolt 11 and the return spring 17, respectively. When the threaded seat 10 is removed, allowing the return spring 17 to return to its natural state, the horizontal axis of the limiting plate 9 is precisely above the top slot of the connecting seat 5. The vertical axis of the limiting plate 9 is connected and fixed to the sliding strip 16. The elasticity of the return spring 17, in conjunction with the locking bolt 11, adjusts the height of the limiting plate 9. Furthermore, during disassembly, the return spring 17 automatically and elastically pushes out of the limiting plate 9, improving the ease of disassembly.

[0025] A movable groove 8 is formed on the side wall of the connecting seat 5 from top to bottom. The depth of the movable groove 8 is the same as the depth of the groove at the top of the connecting seat 5. The sliding strip 16 fits into the movable groove 8. The movable groove 8 and the sliding strip 16 cooperate with each other to allow the scale plate 6 to slide up and down synchronously with the limiting plate 9.

[0026] The ruler plate 6 is made of wear-resistant material, and elevation scales 12 are formed on both sides of the ruler plate 6 in the vertical direction. The elevation scales on both sides are consistent. If the scale on one side is worn during repeated insertion and removal from the soil layer, the data can be obtained by referring to the elevation scale on the other side, thus improving durability.

[0027] The verticality measuring instrument 7 has multiple first connecting screw holes 13, and the scale plate 6 has multiple second connecting screw holes 14. The number of first connecting screw holes 13 and second connecting screw holes 14 are the same and they correspond one-to-one. The first connecting screw holes 13 and second connecting screw holes 14 are used to mate with external bolt threads for detachable connection.

[0028] The verticality measuring instrument 7 is equipped with a digital display screen 15 on the side opposite to the vibrating hammer 1. The digital display screen 15 displays the verticality data detected by the verticality measuring instrument 7, which is convenient for staff to record and adjust.

[0029] The implementation principle of this application embodiment is as follows: When using this device, please refer to... Figure 1 The H-shaped sheet pile 4 to be constructed is clamped by the clamping part 2 of the vibratory hammer 1. Then, the external mechanical arm is connected to the connecting part 3 to control the vibratory hammer 1 to slowly move downward. During the downward movement, the vibratory head of the vibratory hammer 1 continuously vibrates, causing the H-shaped sheet pile 4 and the ruler plate 6 to enter the soil. In addition, the height of the ruler plate 6 can be adjusted by rotating the locking bolt 11 according to construction needs. The insertion depth of the H-shaped sheet pile 4 is observed by observing the elevation scale 12 on the ruler plate 6. At the same time, the verticality data measured by the verticality measuring instrument 7 is displayed in real time on the digital display screen 15. When the deviation of the H-shaped sheet pile 4 is observed, the operator temporarily turns off the vibratory hammer 1 and controls the verticality of the H-shaped sheet pile by swinging the vibratory head of the vibratory hammer 1, thereby realizing the measurement and control of the insertion depth and verticality of the H-shaped sheet pile 4.

[0030] When the device needs to be moved to other pile positions or used in other projects, the worker can pull out the locking bolt 11 by rotating it along the thread. At this time, the limiting plate 9 will slide to the position close to the top of the connecting seat 5 under the elastic action of the return spring 17 at the bottom. Then, the connecting screw 18 can be removed to separate the threaded seat 10 from the connecting seat 5. The limiting plate 9, which has been elastically pushed out, and the key measuring components (scale plate 6 and verticality measuring instrument 7) connected to the limiting plate 9 can be removed naturally. The disassembled components can be transferred to other pile positions and quickly installed with another vibratory hammer 1 with a connecting part 3. It is easy to use without the need for overall transportation.

[0031] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from its essential characteristics. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
